This category collects botany questions covering the study of plants, from cell structure and tissue organisation to physiology, reproduction, genetics and ecology. Use it to test what you remember, spot weak topics and build accuracy before an exam.
Kingdom Animalia members exhibit holozoic nutrition, which involves ingestion and internal digestion. This follows from NCERT principle where relation explains outcome clearly for students.
Ref: NCERT Biology Textbook for Class XI and XII (Botany section), Chapter: Biology - Botany portion covering relevant concept, Topic: Plant structure, physiology and applications.
Hypertrichosis (hairy ears) follows a Y-linked inheritance pattern, as the gene is located on the Y chromosome and is only passed from father to son. This follows from NCERT principle where relation explains outcome clearly for students.
Ref: NCERT Biology Textbook for Class XI and XII (Botany section), Chapter: Biology - Botany portion covering relevant concept, Topic: Plant structure, physiology and applications.
Crossing over occurs during pachytene of prophase I, not in metaphase II. This follows from NCERT principle where relation explains outcome clearly for students.
Ref: NCERT Biology Textbook for Class XI and XII (Botany section), Chapter: Biology - Botany portion covering relevant concept, Topic: Plant structure, physiology and applications.
Abscisic acid induces seed dormancy, helping seeds survive unfavorable conditions. Cytokinins promote, not inhibit, ll division, and ethylene promotes, not delays, fruit ripening.
Ref: NCERT Biology Textbook for Class XI and XII (Botany section), Chapter: Biology - Botany portion covering relevant concept, Topic: Plant structure, physiology and applications.
NADH and FADH₂ donate electrons to the Electron Transport Chain, leading to ATP production through oxidative phosphorylation. This follows from NCERT principle where relation explains outcome clearly for students.
Ref: NCERT Biology Textbook for Class XI and XII (Botany section), Chapter: Biology - Botany portion covering relevant concept, Topic: Plant structure, physiology and applications.
During the S phase, DNA is replicated, doubling the chromosome content of the ll but not the chromosome number. This follows from NCERT principle where relation explains outcome clearly for students.
Ref: NCERT Biology Textbook for Class XI and XII (Botany section), Chapter: Biology - Botany portion covering relevant concept, Topic: Plant structure, physiology and applications.
Cri-du-chat syndrome is caused by a deletion in the short arm of chromosome 5, leading to developmental abnormalities. This follows from NCERT principle where relation explains outcome clearly for students.
Ref: NCERT Biology Textbook for Class XI and XII (Botany section), Chapter: Biology - Botany portion covering relevant concept, Topic: Plant structure, physiology and applications.
Ecosystem services such as water purification, nutrient cycling, and climate regulation are crucial for both ecosystems and human survival. This follows from NCERT principle where relation explains outcome clearly for students.
Ref: NCERT Biology Textbook for Class XI and XII (Botany section), Chapter: Biology - Botany portion covering relevant concept, Topic: Plant structure, physiology and applications.
In dicot seeds like gram and pea, the cotyledons store food and provide nourishment to the embryo. This follows from NCERT principle where relation explains outcome clearly for students.
Ref: NCERT Biology Textbook for Class XI and XII (Botany section), Chapter: Biology - Botany portion covering relevant concept, Topic: Plant structure, physiology and applications.
The cortex of dicot roots consists of parenchymatous lls that store food and nutrients. This follows from NCERT principle where relation explains outcome clearly for students.
Ref: NCERT Biology Textbook for Class XI and XII (Botany section), Chapter: Biology - Botany portion covering relevant concept, Topic: Plant structure, physiology and applications.
Logistic growth is represented by an S-shaped curve, where population growth slows as it nears carrying capacity. This follows from NCERT principle where relation explains outcome clearly for students.
Ref: NCERT Biology Textbook for Class XI and XII (Botany section), Chapter: Biology - Botany portion covering relevant concept, Topic: Plant structure, physiology and applications.
Fungi are heterotrophic, obtaining nutrients through absorption, whereas plants are autotrophic. This follows from NCERT principle where relation explains outcome clearly for students.
